"If only he tried hard enough", "If he only really wanted to heal", "If only we found the right therapy", "If only his defences were down", "There MUST be something good and worthy under the hideous facade", "NO ONE can be that evil and destructive", "He must have meant it differently" "God, or a higher being, or the spirit, or the soul is the solution and the answer to our prayers".
The narcissist holds such thinking in barely undisguised contempt. To him, it is a sign of weakness, the scent of prey, a gaping vulnerability. He uses and abuses this human need for order, good, and meaning - as he uses and abuses all other human needs. Gullibility, selective blindness, malignant optimism - these are the weapons of the beast. And the abused are hard at work to provide it with its arsenal.
